This invention relates to heddle frames for looms and particularlyheddle frames 1n which the heddles are strung on horizontal heddle barssupported at their'ends in sidebars of the frame proper and alsosupported between their ends b links, as hooks, wh1ch in turn aresupporte so as to be free to shift lengthwise of the heddle bars. OneobJect iS to construct a heddle frame which shall be mainly if notentirely of metal, and therefor more ldurable than the ordinary frame 1nwhich usually the top bars of the frame pro er are formed of wood, andwhich shall not of undue weight and not cause interference withadjoining heddle frames in their u and down motion when in use. Anotherogject is to provide for easy attachment and detachment of means wherebyboth to connect the heddle rame to its actuating means and said links tothe heddle frame proper.

In the drawin z Fig. 1 shows t e upper part of a heddle frame embodyingthe lnvention, it being understood that the lower part may be a reversecounterpart thereof' Fig. 2 is an end' elevation;

Fig. 3 a section on line 3-3, F1g. 1;

Fig. 4 a section on line 4--4, Fig. 1;

Figs. 5 and 6 are perspective views of the upper corners of the frameproper;

Fig. 7 is an elevation, partly broken away, of one of the connectors bywhich the heddleframe is attached to its actuating means; and,

Fi 8 is a similar view of a connector by whic a heddle-bar-supportinglink is conneeted to the heddle-frame proper.

The horizontal bar (as illustrated, the top bar) of the frame proper iscomposed of two sheet metal strips 1 1 channeled or longitudinallyrecessed at 2 and having the (iiat) faces of the ribs formed as aconsequence of this channeling secured face to face (Fig: 3), as byspot-welding, and each also havmg its longitudinal edges bent inward asreturned flanges 3, those on one strip spaced from those on the other sothat a contracted mouth or slit 4 exlsts between each two flangeslengthwise of the com leted bar. The pairs of flanges are prefera ly cutaway at 4a, one at one end and the other at the other, to eliminate theflanges or stops for a purpose to appear. The side-bars 5 are flatstrips, each having itsend twisted through 90 degrees from the normaland also rebent (Fig. 2). These rebends or crotches 6 receive the ends 7of the 5; horizontal bar, which ends are flattened (Figs. 4 to 6) andsecured therein by rivets 8, the opposite exterior faces of the rebendsbeing moreover flush with the edges of the remaining or main portions ofthe side bars (Fig. 2), this construction imparting strength andavoiding presence of any projection beyond either vertical face of thehorizontal bar; further the rebends impart a rounded linish to thecorners of the frame. 9 designates the heddle-bar supported at its endsin the side-bars 5 and removably secured therein by hooks 10, all asusual. 9a designates the links, as hooks, by which the heddle bar issupported between its ends.

Each of the mentioned connectors consists of a generally flat memberhaving a catch or catches so that upon forcing it into one of the slits4 of the mentioned horizontal bar its catch will engage and form withthe flanges 3 7 of the bar an interlock opposing return movement of themember. In the illustrated construction of each connector for use inattaching the heddle-frame to its actuating means a plate 11 is rebentupon itself so as to provide an eye or loop 12 at thevbend (which isalso centrally apertured at 13) and each leaf of the plate has a cut-outportion 14 which is bent outward to form the mentioned catch, its freeend forming a locking shoulder and S being directed toward the bend. Astaple 14a havin its ends bent from each other (protrudes rom theaperture 13, its ends being received in the loop 12 (forming anattaching portion therefor), and it forms the means to 90 which toattach the Aconnector to one of the cords or e uivalent means wherebythe frame is actuate The illustrated construction of each connector foruse in attaching the links l 9a to the heddle-frame proper is similar tothat of the connectors already described, to wit, a rebent plate whosebend forms an eye or loop 16 (centrally apertured at 17) has on eachleaf thereof a cut-out portion 18 10 bent outward to form a catch, itsfree end forming a locking shoulder and being directed toward the bend.A fiat pin 19 penetrates the loop (forming an attaching portiontherefor) and has ears 19a holding it from endl wise displacement and italso penetrates the link 9a which is received in aperture 17. It beingunderstood that the catches on the connectors or the mouth portions ofthe horizontal bar or both, have sutlicient resilience l0 to return themwhen distorted from their /normal positions, an of the connectors may beattached to the har by wedging it into the mouth 4 (top or bottom, asthe case may be), and when once forced in until its catches 5 havepassed the flanges 3 it is secure against return; in other words, one ofthe two parts involved has a recess (as the channel of the bar) formedwith a contracted mouth and the other is formed wedge-like and has alocking shoulder (as the free end of catch 14 or 18) engaging said mouthinwardly thereof and opposing withdrawal of the latter part. To removethe connectors they may be slid along the bar until they reach thepointat 4a where the contracted mouth 3 terminates.

Each connector is of greater extent lengthwise of the channel than itsmouth 4 is wide so that it cannot skew appreciably out of a givenpla-ne; in fact its thickness about equals the width of said mouth inthe illustrated construction (Fig. 3).

Having thus fully described my invention what I claim is:

1. In a heddle-frame, a heddle-frame proper including a fiat metalside-bar having its end portion twisted 90 degrees from the normal andrebent and a horizontal bar having its end held in the rebend of thesidebar, opposite exterior faces of the rebend being substantially flushwith the edges of the remaining portion of the side-bar.

y2. In a heddle-frame, a heddle-frame proper including, with ahorizontal bar consisting of a pair of longitudinally channeledsheet-metal strips having their ends flattened and bearing against eachother, a side-bar having its end ,formed with a crotch substantiallyequal in width to the combined thicknesses of and receiving saidflattened ends of the strips.

3. In combination, a heddle-frame proper having a horizontally extendingattaching portion and a connector attached to said u portion, one of theparts formed by said .por-

tion and the connector having a recess receiving the other and suchrecess formed with a. contracted mouth and the other part beingavwedging member and having a locking shoulder engaging said mouthinwardly thereof and thereb opposing withdrawal of said other part romthe first part, said other part being entered into the first partwedge-fashion.

4. In combination, a heddle-frame proper having a horizontally extendingattachlng portion and a connector attached to said portion, one of theparts formed by said portion and the connector havin a channel receivingthe other and such c annel formed with a contracted mouth and the otherpart bein a wedging member and having locking shou der engaging saidmouth inwardly thereof and thereby opposing withdrawal of said otherpart from the first part, said other part being entered into the firstpart wedgeashion.

5. In combination, a heddle-frame proper having a horizontally extendingattaching portion and a connector attached to said portion, one of theparts formed by said portion and the connector having a channelreceiving the other and such channel formed with a contracted mouth andthe other part being a wedging member and having locking shoulderengaging said mouth inwardly thereof and thereby opposing withdrawal ofsaid other part from the first art, said other art being entered intothe rst part wedgeashion and having greater longitudinal extent withinthe channel than the corresponding portion of the channel is wide.

6. In a heddle-frame, a connector for the purpose described consistingof a piece of resilient sheet-metal having a portion for attaching theconnector to one of the elements to be connected and a catch cut out ofand diverted from the normal plane of the piece for attaching theconnector to the other such element.

7. In a heddle-frame, a connector for the purpose described consistingof a piece of sheet-metal rebent on itself to form opposed leaves, thebend affording the portion of the connector for attaching the same toone of the elements to be connected and one leaf having a catchprojecting from the plane thereof, for attaching the connector to theother such element.

8. In a heddle-frame, a connector for the purpose described consistingof a piece of sheet-metal rebent on itself to form opposed leaves, thebend aifording the portion of the connector for attaching the same toone of the elements to be connected andeach leaf having a catchprojecting from the plane thereof for attaching the connector to theother such element.

9 In a heddle-frame, a connector for the purpose described consisting ofa piece of sheet-metal rebent on itself to form opposed leaves, the bendhaving an aperture between its ends, and one leaf havin a catchproject.- ing from the lane thereo in combination with an attac ingmember arranged in the bend and thereby attached to the connector andhaving its own attaching portion at the a erture.
